Description
Technical field
The invention belongs to a kind of vibration test fixture, use this fixture can by after fixing for missile launcher, complete vertical,
The vibration test in three directions of transverse direction and longitudinal direction.
Background technology
Vibration test is a big event in environmental test, can be used to find in product design and production process
Defect, thus reach to improve product design, improve the purpose of the vibration resistance environment capacity of product.
In test chamber, simulated missile, by leading the vibration test of the guided missile sending out the truth that frame is suspended on aircraft, is at present
Effectively examine guided missile and lead the most effective mode sending out frame vibration resistance ability.So a fixing missile launcher need to be made specially
Vibration test fixture.
Summary of the invention
The purpose of the present invention: propose a kind of vibration test fixture, suspension type missile launcher is rigidly connected fixing.
Technical scheme:
A kind of vibration test fixture, including:
Slide block loose slot (1), movable slider (2), outer adjutage (3), connection screw rod (4), pitman (5), ball screw
(6), valve (7)；
Slide block loose slot (1) is screwed onto on cage fixture, by pitman (5) through the hanger of missile launcher, makes hanger
It is in the middle part of pitman (5)；Pitman (5) and two movable sliders (2) are carried out matched in clearance installation；Movable slider
(2) insert from below in slide block loose slot (1)；Connect screw rod (4) by the through hole on slide block loose slot (1) and movable slider
(2) through hole on the U-type groove of both sides and pitman (5) is fixed；In slide block loose slot (1) outside, outer adjutage is installed
(3)；Outer adjutage (3) outside is provided with screwed hole；Valve (7) and ball screw (6) are molectron, and valve (7) can be around bulb
Screw rod (6) one end turns an angle；Ball screw (6) other end is screwed onto in the screwed hole of outer adjutage (3)；Governor valve
(7) position and angle, be fixed missile launcher.
Described vibration test fixture uses 30CrMnSiA as making material.
Advantages of the present invention: being mutually combined and reasonably size design cooperation by several groups of parts, reaches fixing and leads
Play the purpose of launcher, and valve distance and the different length of diverse location can be selected when installing missile launcher flexibly
Spiro rod length install, the technology requirement of fixing identical hanger spacing but various sizes of missile launcher can be met,
It is applicable to the missile launcher of multiple different model, saves the experimentation cost of vibration test.
Accompanying drawing illustrates:
Fig. 1 is the part combination part front view that the present invention fixes hanger.
Wherein: the 1 outer adjutage 4 of slide block loose slot 2 movable slider 3 connects screw rod

Wherein: 6 ball screw 7 valve
Detailed description of the invention:
Below in conjunction with the accompanying drawings the present invention is described in further detail.
The present invention provides a kind of vibration test fixture, as shown in Figure 1,2,3, 4, and including:
Slide block loose slot 1, movable slider 2, outer adjutage 3, connection screw rod 4, pitman 5, ball screw 6, valve 7；
Slide block loose slot 1 is screwed onto on cage fixture, by pitman 5 through the hanger of missile launcher, makes hanger be in
The middle part of pitman 5；Pitman 5 and two movable sliders 2 are carried out matched in clearance installation；Movable slider 2 inserts from below
In slide block loose slot 1；Connect screw rod 4 U-type groove by the through hole on slide block loose slot 1 and movable slider 2 both sides and be connected
Through hole on rod 5 is fixed；Outer adjutage 3 is installed outside slide block loose slot 1；It is provided with screwed hole outside outer adjutage 3；Live
Door 7 and ball screw 6 are molectron, and valve 7 can turn an angle around ball screw 6 one end；Ball screw 6 other end spiral shell
It is connected in the screwed hole of outer adjutage 3；The position of governor valve 7 and angle, be fixed missile launcher.
Described vibration test fixture should use the big material that meets with stresses, and such as uses 30CrMnSiA as making material.
Use process:
The present invention is one group with piece pitman of two slide blocks and is divided into two groups and fixes two hangers respectively.Pitman and slide block
Chute is installed by matched in clearance, and this assembly is seated to slide block loose slot, re-uses screw rod by leading on slide block loose slot
Through hole in the U-type groove of hole and slide block both sides and pitman is fixed；Outer adjutage is installed in the outside of slide block loose slot
And ball screw and the molectron of valve, the concrete position of valve is determined by the selection of position of opening on adjutage outside
Put, thus fixing various sizes of missile launcher.
